I always thought you cannot use a future tense after "until" or "unless". But recently, in a very famous IT system, I found the following:
An estimate of how much work remains until this issue will be
resolved.
Is that correct? Why it is not "until the issue IS resolved"?

I was surprised to encounter a fairly long tradition of use not only of "until it will" but (more specifically) of "until it will be" in English publications, though nothing before about 1770. The Ngram chart of the two phrases for the years 1750–2000 looks like this:
A Google Books search finds a number of early instances. For example, from Charlotte Mason, The Lady's Assistant for Regulating and Supplying Her Table (1777):
From Francis Nicholson, "Process for producing the Lights in Stained Drawings," in The Philosophical Magazine (October 1799):
And from Maria Rundell, A New System of Domestic Cookery (1808):
The phrase "until it will be" began to gain popularity in the 1840s. From William Miller, "The True Inheritance of the Saints," in Dissertations on the True Inheritance of the Saints (1842):
And from notes recorded on February 3, 1842, in Parliamentary Papers, House of Commons and Command, volume 48 (1843):
The Ngram chart above shows an interesting but unexplained increase in the frequency of occurrence of "until it will" from the 1820s until roughly the beginning of World War I, followed by a fairly regular decline until the 1980s.
In modern usage the wording "until it will be" is concentrated in religious—and in particular, Jewish—texts. For example, from Abraham Kook, The Lights of Penitence (1925, reprinted in 1978):
From Isaiah Horowitz & Miles Krassen, The Generations of Adam (1996):
The phrase "until it will" appears in a broader array of contexts, including (as it did long ago) in cookbooks. From Larry Massie & Priscilla Massie, Walnut Pickles and Watermelon Cake: A Century of Michigan Cooking (1990, recipe instructions reprinted from a 1929 source):
And from Paul Wellstone, How the Rural Poor Got Power: Narrative of a Grass-Roots Organizer (1978):
Still, having noted this significant line of usage, I agree with the OP—and with FumbleFingers's comment beneath the question—that "until it will" and "until it will be" are rather unusual forms. The form "until it [present-tense verb here]" is far more common.
